Water quality safety monitoring and early warning system and method based on big data

Abstract

The invention discloses a water quality safety monitoring and early warning system based on big data. The system comprises a water supply station distribution system, a water quality monitoring and early warning system and a pipeline replacement information uploading system; the water supply station distribution system is used for judging distribution conditions of water supply stations according to geographic positions; according to the water quality monitoring and early warning system, the water quality condition in a pipeline is monitored through arranged monitoring nodes, and whether the water quality contains abnormal conditions or not is judged; the pipeline replacement information uploading system detects the change condition of the water quality of the residual chlorine in the pipeline, analyzes whether the pipeline needs to be replaced after being scoured by the residual chlorine so as not to influence the quality of the water in the pipeline, and can reduce the monitoring power consumption, save energy and effectively monitor the water quality by adjusting and setting the monitoring nodes; the time of the monitoring node is calibrated, so that the data time for stopping measurement of the monitoring node is ensured to be synchronous, and the data is ensured to be real and effective.

Description

technical field [0001] The invention relates to the technical field of big data water quality safety, in particular to a water quality safety monitoring and early warning system and method based on big data. Background technique [0002] Tap water has become an important source of human beings, and the country has very strict requirements on tap water flowing out of tap water plants. Strictly control the degree of bacteria or various microorganisms and mixtures in tap water to affect human health. Chemicals containing chlorine are usually used The medicament eliminates the bacteria in the tap water, but when the tap water flows out of the water plant, there is still more than or equal to 0.05mg of residual chlorine in the water to eliminate bacteria and slag in the pipe network, but with the integration of residual chlorine in the water, residual chlorine The gradual dissipation of chlorine in water will not be enough to eliminate the bacteria in the pipe network; therefore,...

[0003] In the paper "Rational Analysis of the Distribution of Water Quality Monitoring Points in Urban Water Supply Networks", published on January 15, 2012, it is stated in the paper that "the number of sampling points for water quality testing in the pipe network should generally be set for every 20,000 population of water supply population. The calculation of one sampling point...should be set at the point where residents often use water, so that large users of municipal water supply should be inspected, effectively avoiding the occurrence of missed inspections, and reaching the foolproof standard." The paper indicated that multiple inspections need to be set The sampling points collect the safety of water quality, but if multiple sampling points are used for monitoring, the power consumption during monitoring will be wasted, but if some monitoring points are closed, the safety of water use cannot be effectively monitored. Therefore, It is necessary to reasonably adjust and set the monitoring points; since the pressure of the water flowing out of the pump is uniform, the impurities in the pipeline will not flow with the water flow, but if the water pump is restarted for a period of time, the water flowing out of the pump will be affected. The pressure is greater than the standard pressure, which can flow the water and impurities in the pipeline together in the water, resulting in more bacteria and impurities in the water, and reducing the quality and safety of the water;
